Country singer and "Dancing With the Stars" contestant Sara Evans is alleging in divorce papers filed Thursday that her husband, Craig Schelske, cheated on her, drank excessively, was verbally and emotionally abusive, and often watched pornography in their house.

The 35-year-old Evans alleges that Schelske has photographs of himself having sex with other women, and that he has at least 100 nude photos of himself "in a state of arousal."

Evans also says that Schelske watched pornography on the couple's computer and made requests online for sex with multiple partners.

She alleges that their oldest child confronted Schelske while he was watching porn on their TV.

Schelske denied his estranged wife's allegations. "I adamantly deny the allegations that are being made," he said in a statement. "As distressing as it is to have to communicate about this matter publicly, Sara has unfortunately become a dramatically different person over the last year and it is something we have struggled to deal with. Sadly, it appears we have failed."

On Thursday, Evans dropped out of "Dancing With the Stars" and announced that she was filing for divorce.

Her music label, Sony BMG, said in a statement that "Ms. Evans felt it was in her children's best interest that she also withdraw from competition on 'Dancing With the Stars' … to give her family her full attention at this difficult time."

Evans and Schelske, 43, married in 1993 and have three children, ages 7, 3 and 2.
